Thank you all for the information!
I guess i shouldn't be too concerned. As i said i ill be using it mostly for gaming, but having the option to upgrade is always nice.
A heads up, the machine I mentioned (see you PM) is a Rev5 NTSC. If you are considering an ACA500 at all, it is probably not the best choice for you.
FYI guys Rev 6 a500s are pretty darn rare in the usa!
No kidding, I've been, perhaps to passively, trying to source a Rev6, or better a Rev8 (A500+) for a year or so, and either miss them, or watch the prices sky-rocket beyond reason. Someday, perhaps, or give in and pay shipping from europe. One or the other.
